I have an .iso of 4.3 gig - do disks that size even exist?

If 7zip works I would use that since its free.

I actually made sure it worked before posting I opened a small linux iso and a large (3.7gig) linux iso

I thought it did, I couldn't remember personally since I don't use it at home. :)

Is this video of the conference? Normally an .iso is a bootable installation file.

I'm not 100% sure on this but I think VLC player will play ISO's without the need to burn or extract.

Quite right. I open .iso files with VLC (usually movies) and they play just as if there were a disc in my optical drive... just quieter!
